The WK2 did a much better job than BMW did in my wife's 128i convertible. In that car, the radio display disappears completely. A poor engineering job IMO, since likely all BMW needed to do was rotate the covering glass piece by 90 degrees (so that it would be polarized on the same plane as user sunglasses - it's the cross-polarization that makes stuff disappear)

Thanks for the feedback. On my Infinitis, I had to buy non-polarized driving glasses for all the reasons mentioned above. I could only see the screens if I looked straight on from directly over the arm rest. Nothing was visible from either front seat.
